2020-07-07android: camera_device: Add buffers for each stream to RequestsKieran Bingham
Construct a FrameBuffer for every buffer given in the camera3Request and add it to the libcamera Request on the appropriate stream. The correct stream is obtained from the private data of the camera3_stream associated with the camera3_buffer. Comments regarding supporting only one buffer are now removed, and FrameBuffers have their lifetime tracked in the Camera3RequestDescriptor to ensure they are released when the Request is completed.

2020-07-06android: camera_device: Maintain a vector of CameraStreamKieran Bingham
Introduce a vector storing a CameraStream to track and maintain state between an Android stream (camera3_stream_t) and a libcamera Stream. Only the index of the libcamera stream is stored, to facilitate identifying the correct index for both the StreamConfiguration and Stream vectors.

2020-06-08android: camera_device: Calculate metadata sizeJacopo Mondi
As we move to have more and more dynamically generated static metadata entries, the size of the metadata buffer has to be calculated dynamically inspecting the information collected from the camera. Provide a method to perform metadata buffers size calculation and use it when generating camera static metadata.

Initialize the stream configuration map by applying the Android Camera3 requested resolutions and formats to the libcamera Camera device. For each required format test a list of required and optional resolutions, construct a map to translate from Android format to the libcamera formats and store the available stream configuration to be provided to the Android framework through static metadata.

2020-06-04android: hal_manager: Do not hardcode propertiesJacopo Mondi
The CameraHalManager::getCameraInfo() method hardcodes the camera facing side and orientation (which corresponds, confusingly, to libcamera's location and rotation properties). Instead of hard-coding the values based on the camera id, inspect the libcamera properties that report the camera location and rotation in a new initialize() method, and use them to report the android camera info and to populate the static metadata buffer.

2020-05-16libcamera: Move internal headers to include/libcamera/internal/Laurent Pinchart
The libcamera internal headers are located in src/libcamera/include/. The directory is added to the compiler headers search path with a meson include_directories() directive, and internal headers are included with (e.g. for the internal semaphore.h header) #include "semaphore.h" All was well, until libcxx decided to implement the C++20 synchronization library. The __threading_support header gained a #include <semaphore.h> to include the pthread's semaphore support. As include_directories() adds src/libcamera/include/ to the compiler search path with -I, the internal semaphore.h is included instead of the pthread version. Needless to say, the compiler isn't happy. Three options have been considered to fix this issue: - Use -iquote instead of -I. The -iquote option instructs gcc to only consider the header search path for headers included with the "" version. Meson unfortunately doesn't support this option. - Rename the internal semaphore.h header. This was deemed to be the beginning of a long whack-a-mole game, where namespace clashes with system libraries would appear over time (possibly dependent on particular system configurations) and would need to be constantly fixed. - Move the internal headers to another directory to create a unique namespace through path components. This causes lots of churn in all the existing source files through the all project. The first option would be best, but isn't available to us due to missing support in meson. Even if -iquote support was added, we would need to fix the problem before a new version of meson containing the required support would be released. The third option is thus the only practical solution available. Bite the bullet, and do it, moving headers to include/libcamera/internal/.

2020-02-13android: Remove internal threadLaurent Pinchart
Now that libcamera creates threads internally and doesn't rely on an application-provided event loop, remove the thread from the Android Camera HAL layer. The CameraProxy class becomes meaningless, remove it and communicate directly from the CameraHalManager to the CameraDevice.

2019-09-05android: camera_device: Fix handling of request templateJacopo Mondi
According to the Android camera HALv3 documentation, the request template metadata pack should not be modified after it is returned to the camera stack from the HAL. Currently, the same metadata pack is used for all types of template request, without updating the capture intent there contained to match the requested template type, as correctly reported by the cros_camera_test test application. In order to avoid modifying the single request template already returned to the camera stack in order to update the capture intent it contains, create a map that associates a dedicated template to each supported capture type.

2019-08-19android: Pass Camera shared pointer to CameraProxy by const referenceLaurent Pinchart
The CameraProxy is constructed with a Camera instance passed through a shared pointer. It forwards it to the CameraDevice constructor, which takes a reference used for the sole purpose of making an internal copy of the shared pointer. Both constructors can thus take a const reference instead of a value or a mutable reference. This optimises the constructors slightly.
